Secondary glazing is an installation of slim-window to the existing windows to form a double-glazed window. It is a cheaper way of insulating and soundproofing the window as well as enhancing security in residential places. Secondary glazing makes the home more energy efficient as it contributes to reducing heat bills. Moreover, it requires less maintenance and is highly durable. Furthermore, it is eco-friendly and help to eliminate the cold drought due to its thermally toughened secondary glass that traps air between itself and existing windows that provide extra insulation to keep the home warmer.

The U.S. Scondary Glazing market was valued at US$ 55.2 Mn in 2022 and is anticipated to grow at a CAGR of 5.25 % during the forecast period (2023 to 2030).

US Secondary Glazing Market - Growth Drivers

  • Increasing demand for energy-efficient windows from residential places

Increasing demand for energy-efficient windows from residential places in the U.S. region is expected to boost the market growth of secondary glazing. Secondary glazing helps to reduce heat bills and acts as the best insulating material to keep the home warmer during cold by trapping the air between itself and the already installed window. Hence, the rising adoption of energy-efficient solutions in the U.S. region is expected to propel the market growth of secondary glazing in the near future.

Market Opportunities

  • The steady growth of the construction industry in the U.S.

The steady growth of the construction industry in the U.S. is projected to boost the demand in the secondary glazing market over the forecast timeframe. According to The Construction Association, the Construction industry is one of the major contributors to United States’ economy and employs around 7 million people in the country. The construction projects handled each year are worth nearly US$ 1.3 million. Hence, the surge in the number of construction projects is expected to propel market growth.

US Secondary Glazing Market – Restraints

  • Strict government rules imposed on the construction

Strict government rules imposed on the construction of new energy-efficient buildings in the U.S. are projected to curb market growth of secondary glazing systems owing to the integration of double and triple glazing systems in the new buildings. The rising number of green buildings in the country due to growing concern over the environment is projected to hinder the market growth of secondary glazing over the forecast period. According to the US Green Business Council’s report, the green building observed 15.1% market growth per year and the overall construction market grew by 9% and reached a revenue of US$ 224.4 billion in 2018 compared to US$ 150.6 billion in 2015.

Key Takeaways

The residential sector dominated the U.S. secondary glazing market in 2018, accounting for US$ 36.8 million in terms of volume, followed by the commercial sector. This is mainly due to a rise in customer inclination towards secondary glazing as it provides a cheaper, more efficient, and sustainable solution for temperature control inside the homes even in extreme weather conditions.

Increasing launch of innovation in secondary glazing products is expected to foster market growth. For instance, in Nov 2019, Fenesta, one of the India's leading manufacturers of Aluminium and UPVC Windows & Doors, launched a range of high-tech UPVC windows and doors with noise-reduction and thermal insulation. Moreover, manufacturers are also focusing on developing products which can withstand extreme weather conditions during winters and can maintain indoor privacy as well.

Market Trends

The growing production of the Low-E storm window is projected to propel the market growth over the forecast period. Window manufacturers in the U.S. country are highly focused on improving their storm window offerings for meeting the rising demand for storm windows with Low-E properties that supports the thermal performance of a building. For example, according to the U.S. Department of Energy, in 2011, Pennsylvania became the first state to integrate Low-E storm windows into its list of priority weatherization measures under its weatherization program.

Players active in the market are Milgard Manufacturing, Pella Corporation, Associated Materials, Jeld-Wen, Kolbe & Kolbe, and Andersen Corporation
